Book Description
Liquid crystal (LC) materials and devices play a central role in numerous established and emerging technologies. This book focuses on several large areas of research including polymer-dispersed liquid crystal technology and twisted smectic materials and applications, as well as nontraditional LC materials and applications. Various aspects of liquid crystal composite technology are featured. Of note is the work concentrating on the use of holography to imprint information into thin films of these systems. Three different approaches for employing holography with liquid crystal materials are discussed. In the ferroelectric liquid crystal arena, the intricacies of different chiral smectic-C architectures are described using detailed X-ray structural experiments on freestanding films. The differences between a molecule and a phase are explored. A number of nondisplay applications using this class of materials are presented and include topics such as adaptive optics, real-time holography and fiber-to-fiber interconnects. Also discussed are glass-forming liquid crystalline films and their ability to polarize photoluminescent emission, their utility in the fabrication of mid-wavelength infrared polarizers, and their utility in the fabrication of bistable electro-optical elements and broadband reflectors.

Book Description
The field of organic optical materials is rapidly growing, and advances are being made both in attaining a deeper understanding of device phenomena and in designing improved materials for thin films, fibers and waveguides. This book offers an interdisciplinary discussion of research on electronic and photonic devices made with organic and polymeric materials. The 1999 MRS Spring Meeting was highlighted by several major advances in fields ranging from nonlinear absorbers and electro-optic polymers, to photorefractive polymers, organic transistors and electroluminescent materials and devices for displays. This book highlights developments in materials chemistry and physics relevant to such devices and strikes a balance between basic science and technology. Topics include: nonlinear optical materials; photorefractive polymers; and electronic and light-emitting materials.

Book Description
Much more than a slight revision, this second edition of the successful "Handbook of Liquid Crystals" is completely restructured and streamlined, with updated as well as completely new topics, 100% more content and a new team of editors and authors. As such, it fills the gap for a definitive, single source reference for all those working in the field of organized fluids and will set the standard for the next decade. The Handbook's new structure facilitates navigation and combines the presentation of the content by topic and by liquid-crystal type: A fundamentals volume sets the stage for an understanding of the liquid crystal state of matter, while individual volumes cover the main types and forms, with a final volume bringing together the diverse liquid crystal phases through their applications. This unrivaled, all-embracing coverage represents the undiluted knowledge on liquid crystals, making the Handbook a must-have wherever liquid crystals are investigated, produced or used, and in institutions where their science and technology is taught. Also available electronically on Wiley Online Library, www.wileyonlinelibrary.com/ref/holc Volume 1: Fundamentals of Liquid Crystals Volume 2: Physical Properties and Phase Behavior of Liquid Crystals Volume 3: Nematic and Chiral Nematic Liquid Crystals Volume 4: Smectic and Columnar Liquid Crystals Volume 5: Non-Conventional Liquid Crystals Volume 6: Nanostructured and Amphiphilic Liquid Crystals Volume 7: Supermolecular and Polymeric Liquid Crystals Volume 8: Applications of Liquid Crystals

Book Description
Materials scientists, polymer chemists, surface physicists and materials engineers will find this book a complete and detailed treatise on the field of polymer brushes, their synthesis, characterization and manifold applications. In a first section, the various synthetic pathways and different surface materials are introduced and explained, followed by a second section covering important aspects of characterization and analysis in both flat surfaces and particles. These specific surface initiated polymerization (SIP) systems such as linear polymers, homopolymers, block copolymers, and hyperbranched polymers are unique compared to previously reported systems by chemisorption or physisorption. They have found their way in both large-scale and miniature applications of polymer brushes, which is covered in the last section. Such 'hairy' surfaces offer fascinating opportunities for addressing numerous problems of both academic and, in particular, industrial interest: high-quality, functional or protective coatings, composite materials, surface engineered particles, metal-organic interfaces, biological applications, micro-patterning, colloids, nanoparticles, functional devices, and many more. It is the desire of the authors that this book will be of benefit to readers who want to "brush-up on polymers".

Book Description
This book on gallium nitride (GaN) and associated materials focuses on advances in basic science, as well as the rapidly maturing technologies involving blue/green light emitters, detectors and high-power electronics. A highlight is a report on wide-bandgap semiconductor research done in Europe. Also reported is the commercialization of a laser operating at 405nm wavelength with a 4000-hour device lifetime. At 450nm emission wavelength, significant reductions in lifetime were found, and are believed to arise from nonideal properties of the InGaN alloy used in the active layer of the device. Additional topics include: the significant success of transistors for microwave applications; improvements in the epitaxy of GaN, using both selective area growth techniques (lateral epitaxy overgrowth) and introducing low-temperature intralayers in the films; advances in both molecular beam epitaxy and metal-organic vapor phase epitaxy, including several studies of quantum dot formation in strained alloys and improvements in hydride vapor phase epitaxy, particularly for providing very thick films.
